Blue front springs and silver rears should see you right on pretty much any UK track you visit - they will be better suited than the kit springs which are quite soft and aimed at US/Dirt tracks. You might want to check out some tyres which are more suitable for UK tracks too - your LHS (Modelsport) should be able to give you good advice.
Give it a run and let us know how it goes - there are loads of people on here who can help with any questions you have
